How to Find your iPhone / iPad / iPod UDID

By : Mario Dabek posted on July 8, 2013

What is the UDID?

Each iPhone, iPad or iPod Touch has a Unique Device Identifier (UDID). This UDID is a sequence of 40 letters and numbers that is specific to your device. It’s like a serial number but much harder to guess.

Why do we need the UDID ?

Your iPhone, iPad, iPod Touch can only install programs that are approved by Apple. However if you would like to try beta Apps or the new iOS Beta firmware before it gets released to the general public, your UDID needs to be on a developer list. Once you’re on the developer list you can go ahead and install the unreleased iOS firmware, and beta Apps.

How do I get my UDID onto a developer list ?

There are a few different ways to get this done.

- register for the $99 Apple developer program and add yourself to your list
- there are various vendors online that sell UDID registration, ranging betweek $ 5 – 10
- get a free registration from us in one of the many weekly contests we run

How do I get my UDID ?

To find your device’s UDID, plug it into your computer and wait for iTunes to recognize it. Select your device in iTunes, and then select the Summary tab. Click on Serial Number to switch to Identifier (UDID) and display your UDID code. Your device’s UDID is not its serial number; these two codes are very different. All UDID codes are 40 characters long.

When the UDID code is displayed, copy it by pressing command+C on a Mac, or control+C on a PC. If checking out with eBay, paste your UDID code in PayPal’s notes or instructions field.
